摘要
A novel colorimetric chemosensor PBIOSi has been designed and synthesized. The addition of F- to a THF solution of PBIOSi resulted in an obvious color change (from red to green) in a short time because of the specific cleavage of Si?O bond in PBIOSi by F-. It was interesting that PBIOSi showed excellent selectivity for F- detection over other halides. The UV-Vis absorption and fluorescence were changed linearly with the concentration of F- over the range of 010 mu mol/L.
